HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 263, 749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 651, 263, 749 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 651, 263, 749 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 651, 263, 749 is 1.

HCF(651, 263, 749) = 1

Highest common factor (HCF) of 651, 263, 749 is 1.

Highest Common Factor of 651,263,749 using Euclid's algorithm

Highest Common Factor of 651,263,749 is 1

Step 1: Since 651 > 263, we apply the division lemma to 651 and 263, to get

651 = 263 x 2 + 125

Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 125 and 263, to get

263 = 125 x 2 + 13

Step 3: We consider the new divisor 125 and the new remainder 13, and apply the division lemma to get

125 = 13 x 9 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 651 and 263 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(125,13) = HCF(263,125) = HCF(651,263) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 749 > 1, we apply the division lemma to 749 and 1, to get

749 = 1 x 749 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 749 is 1

Notice that 1 = HCF(749,1) .
